<para>
|

empty string while a boolean ini value of <literal>on</literal> will

be returned as "1".

<title>When querying memory size values</title>
|
|
<para>
|
|
Many ini memory size values, such as <literal>upload_max_filesize</literal>
|
|
are stored in the &php.ini; file in shorthand notation. <function>ini_get</function>
|
|
will return the exact string stored in the &php.ini; file, <emphasis>NOT</emphasis>
|
|
its integer equivalent. Attempting normal arithmetic functions on these values
|
|
will not have otherwise expected results.
